I noticed on your AM transmitter page that it says you're bringing it back with a new version. What features are in the new version?

I have been interested in AM broadcasting for a while, but I am unable to find high quality transmitters. The only ones available are the low quality ones from Greece. Anyway, I thought I'd make some suggestions.

Maybe use the DDS AD9850 chip instead of PLL VCO (assuming that is what it is now).
Also, it would be nice to have C-QUAM stereo.

Maybe you'd also want to sell linear amps for AM (AFAIK no one seems to sell these). I have a schematic for 100W (400W PEP) AM amplifier using cheap IRFP audio mosfets that work on medium wave band.

I see you have different versions for different frequencies. What is the limiting factor in the frequency range for each model (Is it low pass filter?)
Because I was wondering if I could get one with all frequencies unlocked and then change the filter. Is it possible?

Hi,....in my job I have had discussions with several individuals about AM siting issues. Stations many times lose their land leases or have to sell their land for economic reasons. Landlords and station owners find that the dirt under the AM tower or towers is worth far more for another purpose than as an AM site.
